Abstract:

Objective    Study of fixed orthodontic treatment of enamel demineralization of related risk factors and treatment methods，for clinical provides the basis. Methods    February 2014 to 2016 years 3 months in the hospital for treatment of orthodontic fixed appliance treatment in patients with 116 cases，carries on the analysis to the treatment of patients with associated risk factors by self-made questionnaire，using SPSS 18.0 software to carry on the single factor and multi factor non conditional logistic regression analysis，analyzing of fixed orthodontic treatment of enamel demineralization related risk factors. Results    Fixed orthodontic treatment of enamel demineralization incidence rate and the gender difference was not statistically significant（P > 0.05）；fixed orthodontic treatment of enamel demineralization rate and age，orthodontic treatment，frequency of tooth brushing，containing fluoride toothpaste，eating sweets and drinking carbonated drinks relationship closely（P < 0.05）；fixed orthodontic treatment of enamel demineralization of non conditional logistic analysis showed that the fixed orthodontic treatment of enamel demineralization had a rate with age，poor diet and brushing and orthodontic treatment relationship closely（P < 0.05）. Conclusion    Fixed orthodontic treatment of enamel demineralization of many risk factors，should be based on risk factors to take active and effective measures to deal with and improve the clinical cure rate.

摘要：

目的    研究正畸固定矫治后牙釉质脱矿的相关危险因素及处理方法，为临床提供依据。方法    选取2014年2月至2016年3月福建医科大学附属口腔医院诊治的正畸固定矫治患者116例，采用自拟问卷调查表对患者治疗时相关危险因素进行分析，采用SPSS18.0软件进行单因素和多因素非条件Logistic分析，分析正畸固定矫治后牙釉质脱矿的相关危险因素。结果    正畸固定矫治后牙釉质脱矿发生率在不同性别间差异无统计学意义（P > 0.05），与年龄、正畸疗程、刷牙频率、使用含氟牙膏、饮食甜食及饮用碳酸饮料等关系密切（均P < 0.05）。正畸固定矫治后牙釉质脱矿非条件Logistic分析显示，正畸固定矫治后牙釉质脱矿发生率与年龄、不良饮食习惯、刷牙次数及正畸疗程关系密切（均P < 0.05）。结论    正畸固定矫治后牙釉质脱矿的相关危险因素较多，应根据危险因素采取积极有效的应对措施，提高临床治愈率。
